From 94970014c46223cbcdfbfc67b89596a412f9e3dd Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Fri, 8 Aug 2014 11:00:56 -0400 Subject: [PATCH] nfs: fix error handling in lock_and_join_requests This fixes handling of errors from nfs_page_group_lock in nfs_lock_and_join_requests. It now releases the inode lock and the reference to the head request.
